eBay is making it easier to link to the site from blogs and social networking sites, including from mobile phones as well. The company made the announcement at the eBay Developers Conference and made the tool free to all the 50,000 developers who are registered with eBay. The new tool lets users display related products on their site and requires a ‘call’ to eBay which will now be free, upto 150,000 a month.
